Sloped Roofs
Course 26

About the course

This lesson begins with a review of the way shingles work. Shingles do not seal the roof but rely on movement of water from shingle to shingle to keep the roof free from leaks. Underlayment beneath the shingle and flashing around opens are important parts of the shingle roof system. These issues are covered along with common problems that cause the shingle roof system to fail. One of these is ice damming. An ice dam traps water and allows it to run under a shingle. Preventing ice-dam leaks by using ice shields as underlayment is reviewed. The lesson covers flashing next. Flashing is a common source of leaks and its proper installation is reviewed. The lesson concludes with a discussion of the impact slope has on a roof. Shallow roofs are more prone to ice damming and steep roofs may require installers to use additional safety equipment.
